Low-frequency wideband timing of InPTA pulsars observed with the uGMRT
K Nobleson, Nikita Agarwal, Raghav Girgaonkar +29
High-precision measurements of the pulsar dispersion measure (DM) are possible using telescopes with low-frequency wideband receivers. We present an initial study of the applicatio…
Evidence for profile changes in PSR J1713+0747 using the uGMRT
Jaikhomba Singha, Mayuresh P Surnis, Bhal Chandra Joshi +29
PSR J1713+0747 is one of the most precisely timed pulsars in the international pulsar timing array experiment. This pulsar showed an abrupt profile shape change between April 16, 2…
High Precision Measurements of Interstellar Dispersion Measure with the upgraded GMRT
M. A. Krishnakumar, P. K. Manoharan, Bhal Chandra Joshi +19
Pulsar radio emission undergoes dispersion due to the presence of free electrons in the interstellar medium (ISM). The dispersive delay in the arrival time of pulsar signal changes…
